SCHWARTZ, INCORPORATED, OF PHILADELPHIA, PENNSYLVANIA, .A COR- PORATION OF PENNSYLVANIA.

WARP DRIER.

Application filed November '18, 1924. Serial No. 750,585.

To all whom it may concern:

Be it known that I, EDGAR B. Knns'r, a citizen of the United States, residing in Providence, Providence County, Rhode 'Island, have invented certain Improvements in Warp Driers, of which the following is a specification.

My invention relates to certain improvements in apparatus for drying-warps and strands of other materials, such as tapes,

and small tubular fabrics. 4

One object ofthe invention is to design the drying apparatus so that the warps span the space between two series of supports to 16 allow heated air in circulation todry the warps as it circulates through the space and as the warps are traversed through the apparatus. r

A further object of the invention is to provide means for traversing the warps continuously through" one or more compartments in which air is in circulation.

A still further object of the invention is to provide tension for the warps as they pass through the apparatus.

. The improved apparatus can be used for drying, conditioning and cooling warps, or

other material, if desired.

In the accompanying drawings:-

Fig. 1 is a longitudinal sectional View of a warp drier, illustrating my invention;

Fig. 2 is a transverse sectional view on the line 22, Fig. 1;

ing the means for separating the several strands and warps; I v

Fig. 4 is a sectional perspective view of one of the enameled tu ular warp separafiQ Fig. 5 is a longitudinal sectional view illustrating a form of apparatus, in which the rollers are located outside of the vertical partitions; and

Fig. 6 is a transverse, sectional view of a drier, illustrating a modification of the air circulating means.

Referring to Figs. 1, 2 and 3, the casing 1 of the drier may be of any form desired. In the present instance, it is divided into -30 three compartments a, b and c by: vertical partitions 2 and 3. In the bottom of each 24 in t compartment of the drier is a horizontal partition 4, which has a cyl1ndr1cal openlng for a fan 5. Each fan is mounted on a vertical shaft 6, which is driven by gearing from a longitudinal shaft 7 that extends through one end of the drier casing. On this projecting portion is a belt wheel 8.

In 'the compartment a are two vertical partitions 9 and 10, which are connected to the partition 4 in the lower portion of the compartment. Between the partitions Sand 10 and the ends of the compartment are heating pipes 11 for heating the air circulated by the fan 5. Also within the compartment a, in the rhannel between the two vertical partitions 9 and 10, are two stands of rollers 12 and 13. The stands of rollers are spaced apartso that the warps being dried span the channel through which passes the air in circulation. The rollers of each stand are separated as shown in the drawings. The several rollers are geared together by gear wheels 14, Fig. 2. Each stand is driven by worm gearing (shown by dotted lines in Fig. 1) from a longitudinal shaft 15, which extends through one end of the drier and is provided with a belt pulley 16.

The vertical partitions 9 and. 10 may he made solid, but it is preferred to provide pivoted doors 17 so that access can be had to the warps and rollers when threading the'warpson the rollers. Fig. 3 is an enlarged sectional view, show-' A tension device 19 is provided having series of bars 20, over which the warp threads pass to a roller 21' and into the drier through eyes 22. The warp threads then pass into the partitions 9 in the first com- .partnrent a through eyes 23, after which they pass around the two stands of rollers 12 and 13 and then through an eye 2% in the partition 10 and throughthe partition 2 into the second compartment 1) Where there are stands of rollers 12 and 13 around which the warps pass and through eyes 23, and

1e partitions 9 and 10. The eyes 24s are at the upper end of the partition 10 and the warps pass through these eyes. and through the partition 3 and through eyes 23 in the compartment 0 and around the rollers of thestands 12 and 13". The' warps pass from the rollers through the eyes 24 and out of the drier through the eyes 25.

N ear each stand of rollers are warp separators '26, which are arranged vertically, as shown in Fig. 2. Opposite each roller are transverse warp separators 27. These separato'rs are made of tubes enameled onthe compartments, passing through the coils of heating pipes to the fans.

In some instances, the number of the dry-- ing compartments may be increased or decreased. Onecompartmentmay be a conditioning compartment and another a cooling compartment. In each case, however, the stands of rollers are separated so that the warps span a space through which air is circulated. The heat is regulatedin the ordinary manner and moisture may be added, when necessary.

In the present instance, four warps are passed simultaneously through the drier. The width of the drier depends upon the number of warps that it is 'desired to dry simultaneously. The warps after they pass through the drier are coiled by any standard coiling device.

In Fig. '5 is shown. a drier having a single compartment, in which the stands of rollers 12 and 13 are located in the spaces between the partitions 9 and 10. The warps pass through openings in the partitions, which have a series of hinged doors that can be moved when it is necessary to thread .the warps around the rollers. The fan 5'2 is located in an opening in the partition 4 in the same manner as the fans shown in Fig. 1. This arrangement may be duplicated in a manner similar to that shown in Fig. 1. v

Iii Fig. 6 is shown a modification of the arrangement of the circulating means. In this construction, a longitudinal partition 9 is provided to form acirculating chamber at one side of the drying chamber. In an opening in this partition is a circulating fan 15 which circulates the air in the manner shown by the arrows. The air is heated by a coil of steam pipes 11 in the circulat ing chamber.

I claim:

1. The combination in a drying machine for warps, &c., of a casing enclosing a compartment; means for circulating heated air in the compartment; two stands of rollers spaced apart. and located in said compartment; and means for driving said rollers,

for warps, &c., of a casing enclosing a drying compartment; two stands of rollers in said compartment around which the warps pass as they move through the drying machine; vertical partitions forming channels for the air. in circulation; and a fan for circulating the air.

3. The combination in a drying machine for warps, &c., of a casing enclosing a drying compartment; a horizontal partition near the bottom of the compartment; vertical partitions spaced from each end of the compartment to form a central channel and two end channels; and two stands of rollers located at each end of the central channel having a clear space for the circulation of air, the warps, as they pass through the drying machine, passing around the rollers and across the channels.
